The transmission frequency of CAT6 is 1MHz ~ 250MHz. The PS-ACR of the CAT6 system should have a larger margin at 200MHz, which provides two times the bandwidth of CAT5. The transmission performance of CAT6 is much higher than that of CAT5, which is most suitable for applications with a transmission rate higher than 1Gbps. An important difference between CAT6 and CAT5e is that it improves the performance of crosstalk and return loss. For the new generation of full-duplex high-speed network applications, excellent return loss performance is very important. In the six standards, the basic link model is canceled, and the star topology is adopted in the routing standard. The required routing distance is: the length of the permanent link cannot exceed 90m, and the length of the channel cannot exceed 100m.
